While meeting the China Female Header of the predetermined part of the design, the process forming performance of the material must be considered, and materials suitable for mature production processes, high efficiency and relatively low cost should be selected as far as possible. After the expiration date is used, the re-inspection and approval procedures shall be performed in accordance with the regulations. Beryllium bronze has a higher strength level than tin bronze and brass. With the same grade of material, with different degrees of cold work hardening, the smaller the diameter of the specification, the higher the strength, and the decrease in plasticity.
However, most factories still use bronze plated for parts such as jaws, but parts such as staples, springs and short-circuit rings are usually made of austenitic stainless steel (1Grl8Ni9Ti) stainless steel wire or stainless steel strip. They only think that as long as the finished product passes the inspection, this is very risky. Heat treatment or cold and hot processing deformation can change the organization and structure of metal materials, thereby changing the properties.
In addition, the contact material also requires good processing and formability, uniform internal elasticity, good corrosion resistance, high electrical conductivity, high thermal conductivity and good solderability. 4. Considering the safety of the spacecraft, the electrical connector should be made of non-toxic and flame-retardant materials, or materials that can quickly self-extinguish when burned and rarely produce smoke. 4.
For this reason, each production plant should list the raw material supply list according to the raw materials specified in the design documents of each series of products of the factory as soon as possible, and in general, purchase according to the qualified supply list. 4
